MCP42010T-E/ST

Digital Potentiometers Overview

The MCP42010T-E/ST is a dual-channel digital potentiometer manufactured by Microchip Technology. It features two independent 8-bit wiper positions, providing 256 discrete taps per channel with a nominal resistance of 10 kΩ. The device operates on a single supply voltage ranging from 2.7V to 5.5V and communicates via an industry-standard SPI serial interface supporting modes 0,0 and 1,1. Packaged in a 14-pin Thin Shrink Small Outline (TSSOP) format, it is designed for extended industrial temperature applications, functioning reliably within the range of -40°C to +125°C.

Digital Potentiometers Feature Summary

• Dual-channel architecture with 256 linear tap positions per potentiometer
• SPI serial interface compatible with standard microcontrollers
• Extended temperature range specification (-40°C to +125°C)
• Hardware shutdown pin (SHDN) for power-saving open-circuit mode

Digital Potentiometers Applications

• Volume control and gain adjustment in audio signal processing circuits
• Programmable voltage reference generation
• Digital trimming of analog sensor signals
• Battery management system parameter configuration

Digital Potentiometers Procurement Notes

Verify that the ordering suffix 'T' corresponds to tape-and-reel packaging and 'ST' indicates the TSSOP-14 package variant. Confirm the '-E' suffix aligns with the required extended temperature rating of -40°C to +125°C. Ensure the specific datasheet revision matches the design requirements for electrical characteristics.

Digital Potentiometers Selection Notes

Select this component when dual-channel resistance control is required within a compact surface-mount footprint. The 10 kΩ value suits moderate impedance applications. Verify that the host controller supports the necessary SPI clock speeds, up to 10 MHz at 5V, and provides adequate current drive for the CS and SCK lines.

Digital Potentiometers Part Context

This part belongs to the MCP42XXX family of dual digital potentiometers. It shares core functionality with the MCP42010-I/ST but differs in the temperature grade, where the '-E' variant covers the extended industrial range compared to the standard industrial range of the '-I' variant. The 'T' prefix denotes reel packaging for automated assembly.

Digital Potentiometers Replacement Considerations

The MCP42010-I/ST serves as a functional substitute if the application environment remains within the standard industrial temperature range of -40°C to +85°C. Other members of the MCP42XXX family offer different resistance values or single-channel configurations.
